Time to Transfer as a Quality Improvement Imperative: Implications of a Hub-and-Spoke Health System Model on the Timing of Emergency Procedures.

BACKGROUND: In the increasingly prevalent hub-and-spoke health system model, specialized services are centralized at a hub hospital, while spoke hospitals offer more limited services and transfer patients to the hub as needed. In one urban, academic health system, a community hospital without procedural capabilities was recently incorporated as a spoke. The goal of this study was to assess the timeliness of emergent procedures for patients presenting to the spoke hospital under this model. METHODS: The authors performed a retrospective cohort study of patients transferred from the spoke hospital to the hub hospital for emergency procedures after the health system restructuring (April 2021-October 2022). The primary outcome was the proportion of patients who arrived within their goal transfer time. Secondary outcomes were time from transfer request to procedure start and whether procedure start occurred within guideline-recommended treatment time frames for ST-elevation myocardial infarction (STEMI), necrotizing soft tissue infection (NSTI), and acute limb ischemia (ALI). RESULTS: A total of 335 patients were transferred for emergency procedural intervention during the study period, most commonly for interventional cardiology (23.9%), endoscopy or colonoscopy (11.0%), or bone or soft tissue debridement (10.7%). Overall, 65.7% of patients were transferred within the goal time. 23.5% of patients with STEMI met goal door-to-balloon time, and more patients with NSTI (55.6%) and ALI (100%) underwent intervention within the guideline-recommended time frame. CONCLUSION: A hub-and-spoke health system model can provide access to specialized procedures in a high-volume, resource-rich setting. However, ongoing performance improvement is required to ensure that patients with emergency conditions receive timely intervention.

A low appendiceal mucinous neoplasm lesion in an inflamed appendix within an inguinal hernia.

Amyand's hernia, an incarcerated appendix inside an inguinal hernia, accounts for <1% of hernias in children and even less in adults. Similarly, low-grade appendiceal mucinous (LAMN) lesions are only found in <1% of removed appendices. We present the case of a 72-year-old man with a 15-year history of a large right inguinoscrotal hernia that presented with right lower quadrant pain, was found by computed tomography imaging to have an incarcerated appendix with a large fluid collection, and was post-operatively diagnosed with an LAMN lesion. Although our case is rare due to the simultaneity of the Amyand's hernia and LAMN conditions, each separate condition is prevalent enough for most surgical providers to encounter at least one of these. For our case, we discuss the decisions made in the pre-operative and post-operative management and relevant literature.
